Re: [ADSM-L] Q about TSM 6.1 DB and hardware replication

Grigori,
It should not be necessary to stop your TSM database. DB2 can suspend
IO with the command
set write suspend for db
you can then sync your mirrors and issue
set write resume for db
This will need a DB2 connection rather than a TSM command line, and the
suspend and resume should be issued from the same connection.
How easy is it to access the DB2 instance directly under 6.1?

Hello Wanda,
We have TSM Server 5.5.4.0 under AIX 5.3.
We are mirroring TSM database to disaster site by IBM Metro Mirror (PPRC) for
DS8100.
I have experienced some problems with online mirroring. It means we faced
problems with disaster site activation in case of sending any changes at Head
Office (DB, logs and configuration files) to Disaster Site online (nature of
PPRC). Finally I came to next procedure:
1) complete all backups for current day;
2) complete all copies for current day;
3) run TSM database backup to tape volume;
4) run backups for volume history and device configuration;
5) stop TSM Server;
6) enable mirroring to Disaster Site;
7) wait till both sites are in sync (usually only a few minutes, because we
have two 1Gb/s fiber optics links for mirroring);
8) suspend mirroring;
9) start TSM Server at Head Office and send disaster copy volumes to disaster
site.
In this case, TSM database, logs and configuration files are in sync and they
are in sync with disaster copy of data.
I think, for TSM 6.1 you need to use the same procedure or something similar,
because DB2 will definitely escalate all problems with online mirroring.

Subject: [ADSM-L] Q about TSM 6.1 DB and hardware replication
In prior TSM server versions, replicating the TSM DB and log using hardware
replication works fine as long as the DB and log are in a consistency group.
Any issues with hardware replication of the TSM 6.1 DB and log? With
appropriate changes to dsmserv.opt, will a DR TSM server be able to open the
replicated DB and use it? (Just a little nervous about what all those DB2
services will think..)
Any insight appreciated!
